HARRY E. BREWIN AND ALEXANDER G. MACKEY, OF PLEASANTVILLE, NEW JERSEY DYEING APPARATUS Application filed September 9, 1927.

and moved in such relations as to present all of the yarn to the dyeing liquor without liability of tangling the yarn.

A further object of this invention is the provision of a machine for the support of a plurality of narrow elongated skeins of yarn which may be moved in a novel cooperative relation in subn'ierged relation withina vat of dye liquor.

A further object of this invention is the provision of improved yarn dyeing apparatus including an elevator frame which supports a plurality of skein supporting lreels or movable frames in a novel Icooperative movable relation whereby the skeins may be submerged in the dye liquor and moved to elliciently dye the yarn, and at the same time circulate the dye liquor; the skeins being capable of being removed entirely from the liquor of the dye vat or entirely submerged therein.

Other objects and advantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawings. forming a part of this specilication, and wherein similar reference characters designate ycorresponding` parts throughout the several views,

Figure l is a longitudinal sectional view tal-:en through the dye vat of the improved apparatus. showing the relative positioning of the skein supporting reels or members.

the axle mounting of one of the skein reels and its associated details for driving the reel and properly moving the skein during the dyeing` operation.

Figure 5 is a fragmentary sectional view taken substantially on the line 5 5 of Figure 1, through an adjustable arm of one of the rotary skein supporting reels, showing the mounting thereof.

ln the drawings, wherein for the purpose of illustration is shown merely a preferred embodiment of the improved yarn dyeing apparatus, the letter A may generally designate the improved dyeing machine, which may consist of a stationary frame B, having a vertically slidable and elevating frame C with means D to move the frame C with respect to the frame B for elevating and lowering the skein supporting reels or frames E into Aor completely out of the liquor container or vat L. The reels E are cooperatively supported upon individual brackets F connected upon the elevating frameA C, and are synchronously driven by means K also associated with the frame C and the respective brackets F. Y

Referring to the stationary frame construction B, the same preferably comprises a socket base 10, of cylindrical formation, having a socket opening 11 therein for receiving the lower end of a vertically positioned standard 12, of cylindrical formation;

the standard 12 being suitably non-rotatably attached in the base by means of a transverse pin 14, as shown in Figure 3 of the drawings. The base l1() is of course suitably attached to a foundation 15, in 'any approved manner. The standard 12 at the top thereof is provided with a cap 17, having a bearing 18 thereon which rotatably receives the upper end 19 of a rotary elevating screw 20, comprising part of the means D to be subsequently described.

The elevating frame C includes a sleevelike body 25, provided with a vertical passageway 26 therethrough slidably receiving the post or standard 12 therethrough to permit vertical reciprocation of the body on said post; the tit being sufliciently snug to prevent lateral tipping of the sleeve-like body 25. At opposite sides of the sleeve-like body are platforms 27 horizontally positioned, and braced by means of vertical webs 28, shown in Figure 2 of the drawings, as attached longitudinally beneath the platforms 27 and to the lower portion of the sleeve-like body 25; it being intended that the body 25; platforms 27; and webs 28 be an integral construction. Gf course a portion of the sleeve body 25 extend above the plane of the platforms 27, as clearly shown in Figures 2 and 3 of the drawings. The platforms 27 provide a shelf 27a at the front of the sleeve body 25, as shown in Figure 3 of the drawings; and adjacent the sleeve body 25, with the front thereof, having an enlargement or boss 36, with a vertical. screw threaded opening 31 therethrough, which threadably receives the screw threaded portion of the elevating screw 20, as clearly shown in Figure 3 of the drawings.

Referring to the means D for vertically moving the frame construction B, the same includes a stationary supporting sleeve 35 disposed on the post or standard 12, below the lowermost position which it is desired that the vertically sliding sleeve body 25 shall occupy; the stationary sleeve 35 being keyed by a pin 37, as shown in Figure 3 of vthe drawings, to the post 12. This sleeve 35 is provided with a preferably integral shelf 39, whereon is positioned a bearing 40, for rotatably receiving the lower endA of the elevator screw 20. rfhe bearing may be a step bearing, or as shown in Figure 3 of tl e drawings, the lower end may be open. The shelf 39 extends to the front of the body 35,

where the bearing 40 is provided, ann it alsov extends to a side of the sleeve, as shown in Figure 2 of the drawings, for suppporting a preferably detachable bearing 45., which horizontallysupports a rotatable shaft 46, having a pulley 48 on one end thereof, and having a beveled gear 49 at the opposite end thereof.

Y The elevator screw 20 is vertically positioned at the front of the Vstandard or post 12, and supported in the upper andY lower bearings 18 and 40 above described; the same resting at its lower en d on a thrust bearing 56, shown in Figure 3'of the drawings, which is supported bythe shelf 39. Keyed on the lower end of the elevator screw 20 is a bevel gear 51, which meshes with the gear 49 above described.

Suitable means may be provided for rotating the shaft 46, at intervals, or as desired, and as shown'in dot and dash lines in Figure 2 of the drawings, an individual motor may be employed for driving the pulley 48 thru the intermediary of a belt 56, in order to rotate the elevator screw 2O through the bevelgears 49 and 51, and thus to elevate or lower the supporting reels, with respect to the vat L, as is perfectly obvious from Figures 2 and 3 of the drawings.

The brackets F are individually provided for the reels E, on the frame C and each of the same is vertically depended from the bottom of the shelf portion 27a of the platforms 27, in the relation of details shown in Figures 1 and 3 of the drawings. The brackets F are bolted at to the platforms 27, and at the lower ends thereof the same are provided with enlargedbearings 61 having horizontal passageways 62 therethrough, as clearly shown in Figure 4 of the drawings. Stub shafts 64 are rotatably supported in each of the openings 62, on horizontal axes; the stub shafts 64 projecting forwardly of the bearings 61, and being held in position against longitudinal movement with respect to the bearing at the lower end of the bracket F, by means of forward and rear collars 65 and 66, shown in Figure 4 of the drawings, as keyed on the shafts 64. Between the collars 65 and the facing edge of the bearing 61 is positioned the respective reel E, and the gears for operating the saine.

The reels E are all of the same construction, the same each including an elongated narrow frame body 70, shown in Figures 1, 3, 4 and 5 of the drawings, which intermediate the ends thereof is provided with an apertured hub 71, thru which the shaft 64 of the respective bracket F extends, and is keyed therein at 72. as shown in Figure 4. The frame body of each reel is therefore positioned to be rotatably supported by its respective shaft 64 for movement in a vertical plane, as is clearly shown in Figure 3 of the drawings; the frame body 7 O being mounted at the outer end of the respective shaft 64, as shown in Figure 4. At the outer ends of each of the reel bodies 70, are adapted to be supported rollers or rotatable sticks and 7 6; the latter bein@r adjustable towards or away from the airis of the reel, in order that the reels or frames may receive skeins of various sizes, preferably arranged from skeins of 1 to 24". although such may be departed from.

The roller 75 preferably rotates on a fixed axis, and to this end a shaft 78, shown in Figure 3 of the drawings, is provided, rot-atably be ring in a sleeve 79 integral or rigid with the frame body 70 of the reel E the bearing sleeve 79 extending forwardly at one end normal to the frame body 70, as shown in Figure 3. This shaft 78 is of the desired length, and the roller 75 is keyed at 82 to the saine for rotation with said shaft. At its outer endthe shaft 78 is provided with a keyed collar 83 to receive the roller 75 in position for rotation. and against displacement from the shaft 78. The shaft 78 extends to the opposite or rear side of the respective frame 70 and Y is there provided with sprocket or other wheel 85. keyed thereto and adapted to have trained thereover a belt or llO sprocket chain 86 which is also trained about a preferably stationary sprocket or other wheel 87, shown in Figure l of the drawings; the sprocket wheel 87 being held against any rotation by means of a bracket 89, shown in Figure fl as being attached at 90 to the lower end of the bracket F which supports the stub shaft 64.

Referring to Figure 5, or the detailed mounting of the roller 76 of each of the reels E, it is there shown that a shaft 90 is provided for the adjustable vroller 7 6, the shaft 90 having a rigid flange 91 adjacent one end thereof from the opposite side of which eX- tends a screw threaded shank 92; the arm portion of the body frame of the reel E from the hub 71 being longitudinally slotted at 94 for receiving the screw threaded end 92 g a. nut 95 being provided for adjustment against the frame 7 O to clamp the shaft 90 in a stationary properly spaced and adjusted relation with respect to the aXis of rotation of the frame body 70, as is shown in Figure 5 of the drawings. n this relation the shaft 90 Of course entends forwardly, normal to the frame body 70, and it rotatably supports the roller 76 thereon for free rotation. In order to prevent the roller 76 from detachment from the shaft 90 a. retaining nut and washer 97 and 98, respectively, are provided, as shown in Figure 5. placed over the screw threaded forward end 190 of the shaft 90, although not being clamped too tightly against the forward end of the roller 7 6, as to impede the latters rotation.

Referring to the means K for driving` the shafts 64E, and thru the shafts for driving the reels E, a horizontally positioned main drive shaft 11() is rotatably supported upon the platforms 27, in suitable bearings 111, shown in Figure 1 of the drawings. This horizontal shaft 110 extends the full length of the platforms 27, forwardly of the elevator 20, as shown in Figure 3 of the drawings; the same having a wheel 112 keyed thereon, over which a belt 113, shown in Figure 3 of the drawings, is trained. The motor G is provided with a wheel 114, over which the belt 113 is also trained. and the motor G is supported on one of the platforms 27 to one side of the standard or post 12. as is shown in Figures 1, 2, and 3 of the drawings.

For each of the reels E, a short horizontally positioned shaft 117 is provided, arranged normal to the shaft 110; the same being rotatably supported by suitable detachable bearings 118, forwardly of the shaft 110, as shown in Figure 3 of the drawings. For each of the reels E, bevel gears 120 and 121 are respectively keyed on the shafts 119 and 117, for driving the latter from the main shaft. At the opposite side of the bearing 118 from the bevel gear 121, each of the shafts 117 has keyed therewith a wheel 130, preferably a sprocket Wheel; all of the sprocket wheels screw 20 in rotation.

130 preferably being disposed in the saine plane forwardly of the forward edge of the platforms 27. A sprocket'chain or belt 131 is trained over each of these wheels 130; the said chains or belts 131 at their lower ends being trained about sprocket wheels 135 on the respective shafts 64 of the reels The sprocket wheels 135, as shown in Figure 4, are keyed at 136 on the respective shafts 64,.

Referring to an operation of the ree-ls E, during operation of the motor G, the main shaft 110 is of course rotated, and thru the bevel gears 120 and 121 the counter shafts 117 are of course rotated. Through the belts or chains 131 all of the shafts 64 arerotatedinthe :lo

lower bearing ends of the brackets F, and since the reels E are keyed on the forward ends of said shafts the said reels are bodily rotated in synchronism. Inasmuch as the rollers are keyed to the shaft 7 8 on which they are mounted, and since the chains 86 are trained over the sprocket wheels of said shafts, it is readily apparent that during rotation of the shafts 6d and reels E, (the wheels 87 being held stationary by the brackets 89), a rotation of the shafts 78 of the various reels, on the aires thereof will take place, to rotate the rollers 7 5.

The compact arrangement of the various reels E is well illustrated in Figure 1 of the drawings. It is to be particularly noted that each reel E only includes a pair of the rollers 75 and 76 diametrically opposed at opposite sides of the aXis of rotation of the reel E, so that narrow elongated skeins of yarn may be received on each of the reels between the rollers 7 5 and 76 thereof. The reels E are adjacently arranged with their lengths transverse to each other. In the drawings, the reels E are shown as being H1105 at right angles to each other, with every other reel rotating in the sameV relation. This has been found by us to be the most compact arrangement for the accommodation of a relatively large number of skeins in a small space. It is to be noted that certain alternate brackets F are long-er than the other brackets F, so as to drop the aXes of rotation of the reels supported on the brackets F below the horizontal pla-ne intersecting the axes of rotation of the other reels, as is clearly shown in Figure 1 of the drawings. This enables a closer placing of the skein reels without interference. In dot and dash lines has been shown the paths of rotation* of the rollers of the various reels E, and the direction of rota-tion of the reels. It is apparent that the reels support narrow elongated skeins in a compact relation, the aXis of rotation of the reels intersecting the skeins intermediate the ends thereof.

W'hen it is desired to load the reels E the frame C is elevated by setting the elevating This bodily elevates thevframe C and lifts the reels E out of the iio vat L. The latter is an elongated receptacle, preferably having an open top, and providing a compartment- 150 therein of sufficient depth to permit submergence of the reels E and the skeins respectively supported thereon, within the dye bath, below the liquid level, to substantially the position illustrated in Figure l of the drawings. The vat L is so related to the apparatus that the brackets F may dip into the dye bath, as shown in Figure 3, but if preferred, to prevent deteriorating action of the dyes on the machinery, the operating parts adjacent the brackets F may be properly enclosed. IV hen the reels E are fully elevated from the receptacle L the skeins are placed on the rollers 75 and 76 of each of the reels or rotating frames and it is quite apparent that the skeins of yarn will be narrow and elongated and will not have the cylindrical appearance of the skeins of certain dye apparatus now in conventional use. The motor 55 is preferably a reversible motor, or a reversing clutch may be interposed between the same and the shaft 46, in any of many well known constructions, which will admit of the elevating screw 2O to be reversibly driven for elevating or lowering the frame B, for skein loading of the reels or to ent-irely submerge the skeins below the dye liquor level in the vat. The motor G drives the main shaft ll() very slowly, and it is Vquite apparent that the reels E will be rotated on their shafts 64 in synchronism. Due to the positive rotation of the rollers 7 5 there will be a slow peripheral body movement of the yarn skeins about the rollers 75 and 76, to insure that all parts of the yarn will be contacted by the dyeing liquor.

Due to 'the novel relation in which a large number of the skeins may be compactly moved in entire submergence in the dyeing liquor, there will be a complete and positive penetration of the dyeing liquor within the yarn of the reels so that the apparatus may be well used for processing of different iibers. The close relation of the reels admits of the apparatus creating its own circulation of the dyeing liquor, without other agitating means, and the reels may be rotated very slowly to insure this circulation, due to close positioning of the reels, and there will be no tangling or chafing of the yarn. The machinery may well be used for the dyeing of those types of yarn in which the colors oXidize when removed from the liquor. The novel adjustment of but one arm of each reel admits of the machine taking wide range in sizes of skeins, without alterations to the reels, and the machine will function in the same el'licient relation for operating various sizes of skeins.

Various changes in the shape, size, and arrangement of parts may be made to the form of invention herein shown and oescribed, without departing from the spirit of the invention or the scope of the claims.
